History The rank of löjtnant (sub-lieutenant) appears for the first time during the latter part of the Middle Ages. Originally, it designated the (commander's) deputy, of which the compositions were lieutenant general, lieutenant colonel and captain lieutenant, and sometimes also the lowest commander's deputy. Eventually the word changed to refer exclusively to the company commander's deputy, and even later the rank fänrik (or cornet) for the lowest officer rank was replaced by lieutenant, after which the rank of lieutenant in Sweden was divided into two, löjtnant and underlöjtnant. The fänrik rank was reintroduced in 1914 with the same status as underlöjtnant, but it was subsequently moved one level below underlöjtnant in 1926. Underlöjtnant was removed from the Swedish Armed Forces rank structure in 1937.
